Cleaning and descaling machinery and chemicals A n Internet site posted this question: “How to make descaling solution for different types of scale?” The best answer, chosen by vote, was: “Generally by diluting a concentrated master standard solution of known content, using volumetric bottles. Usually the master solution is diluted 1:10 to 1:100.” The question was declared “Resolved.” This is satisfyingly decisive. But those charged with the cleaning and descaling operation in a modern wire making facility would likely have withheld their vote until they had the answers to some questions of their own: as to materials (steel, stainless, copper, nickel, titanium); processes (plasma, anodic, electrolytic, magnetic, electronic, hydraulic); hybrid functions (descaling/annealing, deglassing, pickling, passivating, corrosion inhibition, sanitation, finishing); plus temperature, salts and acids, thickeners, surfactants, and a host of other descalant concerns. Whether chemical or mechanical, the products and services presented in this section are offered by suppliers who take the comprehensive view of their exacting skill.
